Apple and the carrier must conspire to make IPv6 happen automatically or it doesn’t happen. Because Core Telephony. Grumble grumble grumble.

Yes, this is something I saw with Verizon and my iPad, I was getting IPv6 then some carrier update made it go away and it’s not come back since.

I just got a USA T-Mobile SIM and it does IPv6 properly in a $30 GSM/LTE <-> WIFI and I can get v6 on any device connected.

Quite a stark difference in “does it right” vs “does it wrong”.

I periodically have issues with comcast changing my prefix and hosts not picking them up right, but that’s a bit harder to trace as it happens so infrequently.
